qos template change for backend compute-ai deployment (#16150)
#### Why I did it To enable qos config for a certain backend deployment mode, for resource-type "Compute-AI". This deployment has the following requirement: - Config below enabled if DEVICE_TYPE as one of backend_device_types - Config below enabled if ResourceType is 'Compute-AI' - 2 lossless TCs' (2, 3) - 2 lossy TCs' (0,1) - DSCP to TC map uses 4 DSCP code points and maps to the TCs' as follows: "DSCP_TO_TC_MAP": { "AZURE": { "48" : "0", "46" : "1", "3" : "3", "4" : "4" } } - WRED profile has green {min/max/mark%} as {2M/10M/5%} This required template change <as in the PR> in addition to the vendor qos.json.j2 file (not included here). ### How I did it #### How to verify it - with the above change and the vendor config change, generated the qos.json file and verified that the objective stated in "Why I did it" was met - verified no error ### Description for the changelog Update qos_config.j2 for Comptue-AI deployment on one of backend device type roles
